[0001] The utility model relates to the technical field of hemostasis, and particularly relates to a compression hemostasis component. Background Art
[0002] At present, during clinical treatment, it is necessary to compress and stop bleeding at the wound. For example, in the pediatric hematology-oncology department, there are many wounds that need compression hemostasis, such as after PICC catheter placement, after removal of the infusion port needle, after bone marrow puncture, after lumbar puncture, etc. However, the most widely used compression hemostasis method in clinical practice is still medical staff.
[0003] The inventor's research found that the method of hemostasis by medical staff in the prior art has at least the following disadvantages:
[0004] Medical staff place a sterile gauze block at the puncture wound, and then fix it with a dressing or a bandage. The dressing or bandage cannot automatically apply pressure, and if the patient moves, the gauze block is likely to shift; the gauze block has poor performance in absorbing blood and exudate, is prone to exudation, and increases the risk of wound infection. Summary of the Utility Model
[0005] The purpose of the utility model is to provide a compression hemostasis component, which can improve the effect of compression hemostasis, is not easy to leave the wound, and reduces the infection risk.

The spiral shell-shaped compression member spirals from the inside to the outside in a planar spiral shape, and adjacent spiral coils of the spiral shell-shaped compression member are in contact; the absorbent member is located on the inner side surface of the spiral shell-shaped compression member and is fixedly connected to the middle position of the spiral shell-shaped compression member; the positioning member is located on the outer side surface of the spiral shell-shaped compression member and is fixedly connected to the spiral shell-shaped compression member; the positioning member is used to connect with the patient's body.
[0009] In an alternative embodiment, the absorbent member is provided as a polygonal block, a circular block, or an oval block.
[0010] Based on the above solution, the structure of the absorbent member is diverse, processed as required, and the cost is low.
[0011] In an alternative embodiment, the absorbent member has opposite first and second surfaces. The first surface is adhesively fixed to the spiral shell-shaped compression member, and the second surface is used to contact the patient's skin.
[0012] Based on the above solution, the absorbent member and the volute-shaped pressing member are fixedly connected by an adhesive fixing method. The assembly method is simple and reliable, with a long service life. During use, the position of the absorbent member relative to the volute-shaped pressing member is firm and not easily displaced, and the effects of blood absorption and exudate absorption are good.
[0013] In an alternative embodiment, the absorbent member is provided as a gelatin sponge.
[0014] Based on the above solution, the gelatin sponge is a white or slightly yellowish, light, soft and porous sponge-like substance with water absorption ability, capable of absorbing a large amount of water. Therefore, it can provide good moisturizing effects in wound dressings or facial masks, helping to keep the skin moist and soft. The gelatin sponge contains a certain amount of gelatinase, which can inhibit the reproduction of bacteria, helping the wound to recover and the facial skin to be cleaned. The fibrous network structure of the gelatin sponge and the gelatin substance inside it can form a protective layer at the wound or superficial skin wound, reducing bleeding and relieving the discomfort of the wound surface. The physical properties of the gelatin sponge help prevent scar formation and can absorb excess substances in body fluids, reducing excessive cell secretion.
[0015] In an alternative embodiment, the volute-shaped pressing member includes an elastic strip-shaped sterile cotton yarn, and the strip-shaped sterile cotton yarn spirally winds from the inside to the outside in a planar spiral shape.
[0016] Based on the above solution, the volute-shaped pressing member has a resilience property and can provide an active pressing force to the absorbent member, thereby stably fixing the absorbent member at the wound position.
[0017] In an alternative embodiment, the outer end of the strip-shaped sterile cotton yarn is sewn and fixed to the spiral coil near the inner side of the outer end.
[0018] Based on the above solution, after the strip-shaped sterile cotton yarn is spirally wound and the outer end is fixed, the stability of the spiral structure can be ensured, it is not easily loosened, and a continuous and stable automatic pressing force can be provided.
[0019] In an alternative embodiment, a part of the positioning member protrudes from the volute-shaped pressing member, and an adhesive layer is provided on the part of the positioning member protruding from the volute-shaped pressing member, and the adhesive layer is located on the side of the positioning member close to the volute-shaped pressing member.
[0020] Based on the above solution, an adhesive layer is provided on the positioning member. After the absorbent member and the volute-shaped pressing member are arranged at the wound position, the adhesive layer on the positioning member is used to contact the patient's skin, so that the absorbent member and the volute-shaped pressing member are fixed relative to the wound, and the hemostatic effect is good.
[0021] In an alternative embodiment, a peelable layer is provided on the positioning member, and the peelable layer covers the adhesive layer.
[0022] Based on the above solution, before the adhesive layer is used, the peeling layer covers the adhesive layer, so that the adhesive layer is not easily contaminated or damaged, the adhesion of the adhesive layer is not easily reduced, and the firmness of contact with the skin can be improved, thereby improving the fixing effect.
[0023] In an alternative embodiment, an operating portion protruding beyond the edge of the adhesive layer is provided on the peeling layer.
[0024] Based on the above solution, when it is necessary to peel the peeling layer from the adhesive layer, since the operating portion does not contact the adhesive layer, it is convenient for the operator to hold the operating portion and apply force to the operating portion to drive the entire peeling layer away from the adhesive layer, reducing the operation difficulty and improving the operation convenience.
[0025] In an alternative embodiment, the operating portion is located on the side of the adhesive layer close to the spiral-shaped pressing member.
[0026] Based on the above solution, the operating portion is located inside the adhesive layer, and the peeling layer gradually leaves the adhesive layer from the inside out. While the adhesive layer is gradually exposed, the adhesive layer can be gradually pasted on the skin from the inside out, which is convenient for operation.

At the same time, the spiral-shaped pressing member contacts the skin, and the spiral-shaped pressing member is fixed on the skin by the positioning member. Pressure is applied to the absorbent member through the spiral-shaped pressing member to ensure that the absorbent member is aligned with the wound. Since the spiral-shaped pressing member has a spiral structure that spirals outwards in a planar spiral shape from the inside out, it has a certain elastic force to restore deformation by itself, thereby providing a certain active pressing force to the absorbent member, improving the stability of the absorbent member relative to the wound position, and it is not easy for the absorbent member to shift when the patient moves, and the absorption effect and hemostasis effect are good.

[0041] In the prior art, medical staff generally place sterile gauze or cotton pads on the wound and use fixing components such as dressings or bandages for fixation. The dressings or bandages cannot automatically apply pressure, and if the patient moves, the gauze block is likely to shift; the gauze block has poor performance in absorbing blood and exudate, is prone to exudation, and increases the risk of wound infection.
[0042] In view of this, the designer provides a hemostatic compression assembly with high stability, not easy to move, good hemostatic effect, and low risk of wound interference.
[0043] Please refer to Figures 1-3 In this embodiment, the hemostatic compression assembly includes an absorbent member 100, a spiral shell-shaped compression member 200, and a positioning member 300. The spiral shell-shaped compression member 200 spirals from the inside to the outside in a planar spiral shape, and the adjacent spiral coils of the spiral shell-shaped compression member 200 are in contact; the absorbent member 100 is located on the inner side surface of the spiral shell-shaped compression member 200 and is fixedly connected to the middle position of the spiral shell-shaped compression member 200; the positioning member 300 is located on the outer side surface of the spiral shell-shaped compression member 200 and is fixedly connected to the spiral shell-shaped compression member 200; the positioning member 300 is used to connect with the patient's body.
[0044] Based on the above solution, the usage method of the hemostatic compression assembly provided in this embodiment includes, for example:
[0045] When wound hemostasis is required, align the absorbent member 100 with the wound position so that it presses on the wound. At the same time, the spiral shell-shaped compression member 200 contacts the skin, and the spiral shell-shaped compression member 200 is fixed on the skin by using the positioning member 300. Pressure is applied to the absorbent member 100 through the spiral shell-shaped compression member 200 to ensure that the absorbent member 100 is aligned with the wound. Due to the spiral structure of the spiral shell-shaped compression member 200 that spirals from the inside to the outside in a planar spiral shape, it has a certain elastic force for restoring deformation, thereby providing a certain active compression force to the absorbent member 100, improving the stability of the absorbent member 100 relative to the wound position, and it is not easy for the absorbent member 100 to shift when the patient moves, with good absorption effect and good hemostatic effect.
[0046] The following embodiments illustrate the details of the hemostatic compression assembly provided in this application by way of examples.
[0047] In this embodiment, optionally, the absorbent member 100 is provided as a polygonal block, a circular block, an oval block, or the like. It should be understood that the structure of the absorbent member 100 is designed according to requirements, with low processing costs, and the structure of the absorbent member 100 is diverse, which can be selected according to needs, is flexible and changeable, and has low usage costs.
[0048] In this embodiment, optionally, the absorbent member 100 has opposite first and second surfaces. The first surface is adhesively fixed to the volute-shaped pressing member 200, and the second surface is for contacting the patient's skin.
[0049] It should be noted that the absorbent member 100 and the volute-shaped pressing member 200 are fixedly connected by an adhesive fixing method. The assembly method is simple and reliable, with a long service life. During use, the position of the absorbent member 100 relative to the volute-shaped pressing member 200 is firm, not easily displaced, and has a good effect of sucking blood and absorbing exudate.
[0050] In an alternative embodiment, the absorbent member 100 may be provided as a gelatin sponge.
[0051] It should be noted that the gelatin sponge is a white or slightly yellowish, light, soft and porous sponge-like substance, which has water absorption and can absorb a large amount of water. Therefore, it can provide a good moisturizing effect in wound dressings or facial masks, helping to keep the skin moist and soft. The gelatin sponge contains a certain amount of gelatinase, which can inhibit the reproduction of bacteria and help the wound recover and the facial skin clean. The fibrous network structure of the gelatin sponge and the gelatin substance inside it can form a protective layer at the wound or superficial skin wound, reducing bleeding and relieving the discomfort of the wound surface. The physical properties of the gelatin sponge help prevent scar formation and can absorb excess substances in body fluids, reducing excessive cell secretion.
[0052] In this embodiment, optionally, the volute-shaped pressing member 200 includes an elastic strip-shaped sterile cotton yarn, and the strip-shaped sterile cotton yarn spirals from the inside to the outside in a planar spiral shape. That is to say, the volute-shaped pressing member 200 is formed by winding a strip-shaped sterile cotton yarn from the inside to the outside in a spiral shape. The volute-shaped pressing member 200 has a spiral structure, which is convenient to prepare, has a compact structure, and can provide a stable pressing force, thereby stably fixing the absorbent member 100 at the wound position.
[0053] In this embodiment, optionally, the outer end 210 of the strip-shaped sterile cotton yarn is sewn and fixed to the spiral coil near the inner side of the outer end 210. It should be noted that after the strip-shaped sterile cotton yarn spirals, fixing the outer end 210 can ensure the stability of the spiral structure, not easily loosen, and can provide a continuous and stable automatic pressing force.
[0054] In this embodiment, optionally, a part of the positioning member 300 protrudes from the spiral housing-shaped pressing member 200, and an adhesive layer 310 is provided on the part of the positioning member 300 that protrudes from the spiral housing-shaped pressing member 200. The adhesive layer 310 is located on the side of the positioning member 300 close to the spiral housing-shaped pressing member.
[0055] It should be noted that an adhesive layer 310 is provided on the positioning member 300. After the absorbent member 100 and the spiral housing-shaped pressing member 200 are disposed at the wound position, the adhesive layer 310 on the positioning member 300 is used to contact the patient's skin, so that the absorbent member 100 and the spiral housing-shaped pressing member 200 are fixed relative to the wound, and the hemostatic effect is good.
[0056] In this embodiment, optionally, a release layer 320 is provided on the positioning member 300, and the release layer 320 covers the adhesive layer 310.
[0057] It should be noted that before the adhesive layer 310 is used, the release layer 320 covers the adhesive layer 310, and the adhesive layer 310 is not easily contaminated or damaged, and the adhesion of the adhesive layer 310 is not easily reduced, which can improve the firmness of contact with the skin, thereby improving the fixing effect.
[0058] In this embodiment, optionally, an operation part 321 protruding from the edge of the adhesive layer 310 is provided on the release layer 320.
[0059] It should be noted that when the release layer 320 needs to be peeled off from the adhesive layer 310, since the operation part 321 does not contact the adhesive layer 310, it is convenient for the operator to hold the operation part 321 and apply force to the operation part 321 to drive the entire release layer 320 away from the adhesive layer 310, reducing the operation difficulty and improving the operation convenience.
[0060] In this embodiment, optionally, the operation part 321 is located on the side of the adhesive layer 310 close to the spiral housing-shaped pressing member 200.
[0061] It should be noted that the operation part 321 is located inside the adhesive layer 310, and the release layer 320 gradually leaves the adhesive layer 310 from the inside to the outside. While the adhesive layer 310 is gradually exposed, the adhesive layer 310 can be gradually pasted on the skin from the inside to the outside, which is convenient for operation.
[0062] It should be understood that after the positioning member 300 is fixed on the spiral housing-shaped pressing member 200, both sides of the positioning member 300 protrude from the edge of the spiral housing-shaped pressing member 200. Thus, there are two adhesive layers 310 on the positioning member 300 located on both sides of the spiral housing-shaped pressing member 200, and each adhesive layer 310 is correspondingly provided with a release layer 320. By respectively tearing the two release layers 320, the two adhesive layers 310 can be exposed, so as to facilitate fixing the spiral housing-shaped pressing member 200 on the skin by using the positioning member 300.
[0063] It should be understood that in other embodiments, the positioning member 300 can also be set as a sticky 3M transparent dressing, which plays a role in shaping and fixing. The transparent dressing is set in a structure with air bubble holes. Before use, the air bubble holes are in a compressed state and are unlocked when pasted and used. Each air bubble hole is inflated to form a closed structure, and at this time, a compressive force is formed to play a role in compressive hemostasis.
[0064] For the compressive hemostasis assembly provided in this embodiment, the absorbent member 100 is aligned at the wound, and the volute-shaped compressive member 200 and the absorbent member 100 are fixed relative to the wound through the positioning member 300. The volute-shaped compressive member 200 has a certain ability to recover from deformation, so as to provide an active compressive force for the absorbent member 100. The absorbent member 100 is not easily displaced, and the absorption effect and hemostasis effect are good.
[0065] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications.
